Otters can attack and harvest while riding on your shoulder. The damage it deals isn’t much compared to other natives of the Island, but it’ll definitely help to kill the enemy before they kill you. Just watch out for the pikes or spears.
Helpful Tip: Did you know you can hatch eggs using these mfs? First, tame 3 otters, place them in a triangular shape with the egg in the center, then BOOM!! u got yourself a baby dino. Nature's incubator.
